Only small remains of the castle of Wiprecht of Groitzsch on Burgberg ('Castle Hill') are still visible, but the site has been investigated archeologically and is protected as a historical monument.
The Wiprechtsburg is situated on the northwestern edge of the town of Groitzsch and was one of the largest castle complexes in Saxony around 1100 under Count Wiprecht von Groitzsch. A special feature is the oldest stone building in Saxony, the round chapel built by Wiprecht for his wife (daughter of the Bohemian duke Vratislaw II) based on the Bohemian model.
During the summer months the area is used as an open-air stage for concerts and other events.
From Groitzsch, Wiprecht II fought many of his battles for the right to rule and land and continued to build up his power. The once mighty castle was destroyed in 1306. Only parts of the Romanesque round chapel and a residential tower built around 1080 have survived.
Extensive excavations by archaeologists from 1954 to 1968 uncovered the remains of the residential tower and the round chapel and brought to light valuable findings on the history of the castle.With the completion of the excavations, the design of the entire castle area began. An open-air stage was built in the ruins, a vineyard with more than 500 vines, flower beds and hiking trails along the castle mountain and along the banks of the Schwennigke river. Today, 48 exhibits from the immediate vicinity are on display in one of the stone lapidarium corridors. In the summer months, numerous events take place at Wiprechtsburg Castle, the broadcasting of which reaches beyond national borders, e. g. the summer solstice celebration, open-air concerts, and the annual castle festival, to name but a few.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
